okay so i've posted here before (when i was trying to get over the breakup) but on the weekend i went to a party and my ex (of a month and a half) was there and so basically my best friend ditched me to hang out with him for the entire night, they were with everyone else, i was right there and they were flirting really obviously and infront of everyone... i was really uncomfortable, and kind of hurt that she did that, but no one believed i was actually sick.. most people just thought i was faking it and that i was actually really jealous.. ANYWAY so she was coming back to my house for a sleepover and ended up in tears because she found out that everyone was pissed off at her for doing what she did, i reassured her and told her i wasnt angry or anything, but at school she still thought i was so i wrote her a letter explaining everything like why i was upset at the party but that i wasnt anymore and it was all cool and i was over my ex anyway. but then he started getting involved, i messaged him trying to explain any misunderstandings that i was upset and angry at them, and he begs me to tell him why i was upset, so i had to spell it out for him (it isnt hard to understand), then he said he was sorry and they didnt realise but that he heard i was hard on her after the party and that pissed him off, SO i explained how i wasnt at all... but thats not all the next day he went up to her and told her everything i told him but twisted my words to make it sound like i was bitching about her, and then he walked home with her, only to talk about it again! i really don't know why he cares so much and it's just getting annoying now.. its like he wants there to be a fight about him so hes stirring it up! what should i do??
